ATTACHMENT FOR SEEDERS.

Specification of Letters Patent.

Application filed September 9, 1909.

ltatented J an. 25, 1910.

Serial No. 516,822.

To all whom it may concern:

Be it known that T, HOWARD BROWN, a native-born citizen of the UnitedStates, residing at Buffalo, in the county of Johnson and State ofWyoming, have invented certain new and useful Improvements inAttachments for Sowers, of which the following is a specification.

My invention relates to an improvement in an attachment to broadcastseed sowers.

The object is to provide means whereby the chain which connects thedriving shaft of the sower with the sprocket wheel on the wheel of thevehicle may be easily removed or applied to the sprocket wheels.

The invention consists of certain novel features of construction andcombinations of parts which will be hereinafter described and pointedout in the claims.

In the accompanying drawings: Figure l is a top plan view; Fig. 2 is adetailed view of the shaft and supporting arm; Fig. 3 is a detailed viewof the supporting arm and bracket and Fig. 4 is an end view of thebracket.

A represents the end board of a wagon upon which is supported the seedsower B. The driving shaft 1, of the sower, is made in two pieces, andthe ends of the two sec tions are connected together by bolts 2, 2. Theouter end of the shaft is supported by an arm 8, which is connected tothe end board of the wagon. A bracket & is provided with an openingtherethrough through which the shaft tongue extends, and the bracket ispivotally connected to the arm 3 as at 5. Loosely mounted upon the shaftis a sprocket wheel 6, which is adapted to engage the usual form ofclutch 7 for locking the sprocket wheel upon the shaft when it isdesired to transmit motion to the shaft and the operative parts of thesewer. A wheel 0 on the wagon is provided with a sprocket wheel 8, overwhich a chain 9 passes, and the chain extends over the sprocket wheel 6so that as the wheel C revolves the sprocket wheel 6 is caused torotate, transmitting mo tion to the shaft 1.

The operative parts of the sewer form no part of my invention and henceI have not described the manner of operation.

The chain 9 is often difficult to place over the two sprocket wheels 6and 8, the great trouble being that the chain is either too long or tooshort, and when put on too tight the'chain will be broken and when tooloose the shaft 1 is not properly operated. To overcome the objection ofplacing the shaft upon the two sprocket wheels, I have so journaled onesection of the shaft 1 that it can be swung outwardly, whereby the chaincan be slipped over both sprocket wheels very readily. The shaft can bethen swung back into position and be connected up to the other sectionby the bolts 2. The bracket l, which is pivotally connected to the arm 3permits of the outer end of section of the shaft being swung to permitof the chain being placed upon the sprocket wheels or to remove thechain from the sprocket wheels by simply disconnecting the two sectionsof the shaft 1.

From the foregoing it will be seen that I have provided a very simplemeans of applying the chain to the sprocket wheels and permitting thechain to be removed at any time for repairs or when it is desired tostop the operation of the sewer.

Having fully described my invention what I claim as new and desire tosecure by Letters Patent, is: i

1. The combination with a vehicle body, of a seed sower mounted thereonhaving a drive shaft made in sections, one section of the shaftpivotally mounted upon the vehicle body, and means for connecting thetwo sections of the shaft together.

2. The combination with a wagon body, of a seed sower mounted thereonhaving a drive shaft made in sections, an arm mounted on the wagon body,a bracket pivotally connected to the arm for supporting one section ofthe shaft and means connecting the sections of the shaft together.

3. The combination with a vehicle having a body and wheels, a sprocketwheel on one of the wheels, of a seed sower mounted on the vehicle body,having a drive shaft made in sections, an arm connected to the vehiclebody pivotally supporting one section of the shaft, means connecting thesections of the shaft together, a sprocket wheel on the shaft and achain connecting said sprocket wheel and the sprocket wheel on thevehicle wheel.

In testimony whereof I affix my signature, in the presence of twowitnesses.
